Ok, so I'm new here and just bought my 2DSxl. Because I had a DS lite with a flashcard, I wanted to play my old Roms. Thats why I ordered an R4 flashcard as well. I followed a guide on how to install a cfw that I can play Rom from my flashcard. I followed every step, but it said that my 2Ds couldnt find a backup.bin file. I was told to rename it but i looked on my PC. It was not there. So, I asked for help and waited. No answer. I thought if I factory reset my 2DS I could give it a new shot. So I did. But now after I reset I read something with luna and my DS crashed after starting Mario card DS (actually bought and legit game). I tried to redo the whole process, but it seems like the reset was not successful, because my 2DS boots differently as it did the first time. And in the settings it says sys 11.7 and not version 11.7. How can I reset my DS the fastest and easiest way? Thank you for reading and hopefully helping me.
